Who is the man behind the mask in Zoom's lair? That is the big question hanging over The Flash as the series heads toward its Season 2 finale, and star Carlos Valdes promises the reveal will be satisfying.

"I think all the curtains will be drawn and all mysteries will be revealed in terms of Zoom origin, the lair, the Man in the Mask, the identities," he told IGN of how Season 2 will be resolved. "There's an element that's missing that people don't know about yet in which people won't find out about until the Man in the Iron Mask is unmasked."

When asked if he found the reveal to be satisfying or whether this storyline would continue into Season 3, Valdes explained that the identity of the Man in the Mask won't make sense until you get his whole story.

"When I first found out who it was, I was thrown for a loop," Valdes said. "You don't understand why it's this person until you go into the story behind how this person got into the cell, why Zoom took them hostage and put them in the cell. You cannot make sense - there's no way of making sense of why that person is in the mask until it is explained. But I think that explanation is very satisfactory. It takes loops and turns, and it's a riveting story that makes sense within Zoom's chronology and his story and his motivations."

He added, "The payoff after the unveiling of the mask as far as that character is concerned, there's this beautiful reveal. It's just a beautiful reveal. That's all I'm going to say."

The Flash airs Tuesdays at 8 p.m. ET/PT on The CW.
